Article entity
Similarly, in the Article entity, add named queries to find all Article entities and
find an Article entity by ID. Add @ManyToOne annotations to define the many-to-
one relationships between the Article entity and the Edition and Section entities.
The Article entity is listed as follows:
package model;
import java.io.Serializable;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
